1. 16. Dialectical Dimensions on Inclusive Education : Involving Students with Autism Spectrum Conditions

   Författare :Johanna Lüddeckens; Lotta Anderson; Daniel Östlund; Nina Klang; Malmö universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; inclusive education; autism spectrum conditions; inclusive school leadership; principals; dialectical approach; dilemma perspective; school organization.;

   Sammanfattning : Purpose: The aim of this essay and its contribution to research is to identify the opportunities, pitfalls, and dilemmas that can arise when inclusive education is organized with regard to students with ASC. In order to create more understanding of the situation for students with ASC in schools, the study focus on school leadership. LÄS MER

3. 17. Degradation of railway rails from a materials point of view

   Författare :Martin Schilke; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anisotropy; White etching layer; Rail grade; Rolling contact fatigue; Three dimensions; Plastically deformed layer; Railway Rail; Crack;

   Sammanfattning : From time to time railway rails need to be replaced. In that case and when new track is built, a decision has to be made about which rail grade that is going to be installed. The intention of this work was to compare different rail steels concerning their suitability from a mechanical durability perspective. LÄS MER

4. 18. Initial Business Models in New Technology-Based Firms: Dimensions and Founders' Prioritisations

   Författare :Hanna Rydehell; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; measurable dimensions; prioritisation; new technology-based firm; business model; cognitive instrument;

   Sammanfattning : Business models have been emphasised in research as an important concept for studying and understanding firms’ value creation and performance. The business model in literature is understood as how firms configure their businesses, including how they create and deliver value for their customers, and how they capture economic value from its offering.

5. 19. On Steady Water Waves and Flows with Vorticity in Three Dimensions

   Författare :Douglas Svensson Seth; Partiella differentialekvationer; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; The steady Euler equations; the water wave problem; fluid dynamics; partial differential equations;

   Sammanfattning : In this thesis we study the steady Euler equations in three dimensions where the solution is assumed to have nonvanishing vorticity. The thesis is based on three research papers. LÄS MER

7. 20. Nearest Neighbor Classification in High Dimensions

   Författare :Sampath Deegalla; Henrik Boström; Slawomir Nowaczyk; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nearest Neighbor; High-Dimensional Data; Curse of Dimensionality; Dimensionality Reduction; data- och systemvetenskap; Computer and Systems Sciences;

   Sammanfattning : The simple k nearest neighbor (kNN) method can be used to learn from high dimensional data such as images and microarrays without any modification to the original version of the algorithm. However, studies show that kNN's accuracy is often poor in high dimensions due to the curse of dimensionality; a large number of instances are required to maintain a given level of accuracy in high dimensions.
